Embodiment 1

[0022] Embodiment 1: The wire harness of this embodiment has no branch structure.

[0023] First, use a steel rod with a diameter equivalent to the wire harness to make an under-vulcanized sleeve, coat the vulcanized rubber on the steel rod and heat it for vulcanization, and stop heating when it is not fully vulcanized. The vulcanized rubber forms an under-vulcanized sleeve on the surface of the steel rod, and then Cut the under-vulcanized casing and peel it from the steel rod. Cut the undercured casing in a straight line from the axial direction.

[0024] The cable is straightened out by one-time forming tool. The one-time forming tool includes a groove plate and connectors at both ends. A straight groove is opened in the center of the groove plate. There are notched grooves at both ends of the straight groove. A connector is installed at the notch, and after the connector is placed in the notch groove, there is a ring of protruding edges on the outer contour of the connecto...

Embodiment 2

[0025] Embodiment 2: The wire harness of this embodiment has a branch structure

[0026] Use one-time forming tool to locate through each connector flange groove, design one-time forming tool, including groove plate and connector, groove plate has two positioning grooves, one straight groove and one inclined groove. Set the spacing between the flange positioning grooves of each connector to a certain length, and the width of the middle wire harness groove is equal to the diameter of the wire harness. After the first connector is made and the glue is stacked, the second and third connectors are made. The cable semi-finished product starts from the first end, and gradually places the connector and wire harness in the one-time forming tool. When placing the second or third connector, push the connector back to place the flange in the groove of the positioning flange, and connect the second end. The device is used to install the branch point of the cable harness, plug the extra ca...

Abstract

The invention discloses a vulcanization method for a cable harness. First, the vulcanized rubber is coated on a steel rod for heating and vulcanization, and the heating is stopped when the complete vulcanization state is not reached. The sleeve is peeled off from the steel rod, and finally the vulcanized sleeve is put on the cable harness and heated to complete the vulcanization. The invention can solve the problems of uneven encapsulation and uneven stress and deformation of the wire harness, and completely solves the problem of the vulcanization eccentricity of the cable wire harness from the technological method.

Description

technical field [0001] The invention belongs to the technical field of cable vulcanization, mainly relates to a treatment method for preventing the vulcanization eccentricity of a multi-head cable harness, and belongs to the category of cable assembly. Background technique [0002] In the existing cable harness manufacturing method, due to the flexibility of the harness and the effect of uneven pressure during the vulcanization process, the cable is prone to unqualified phenomena such as eccentricity of the harness and even leakage after vulcanization. The main reasons are: [0003] a. Due to the difference of each wire, the same repairing size will also cause the length error between the cable products. Since the vulcanization process is based on the positioning of the connector flanges on both sides, a long cable harness will appear in the mold during vulcanization molding. The redundant part is bent and deformed; [0004] b. The cable harness is composed of soft wires, a...
